Hi Coach White, welcome to the Grey family! As to shoulder sitting, its all up to you. Do you enjoy your parrot in your shoulder?? If so, it's great. If not, then you should curb Ziggy's desire to go there. It's all up to you. As long as my parrots don't nibble my ears, I have no problems with shoulder sitting. That's one of the very nice things about having a flighted companion, if you don't want them on your shoulder a quick flick of the shoulder and off they go! I look forward to hearing about your new friend!!!
